For the neonatal patient, precocity of diagnosis is crucial for effectiveness of medical approach. However, the newborn has its own physiological peculiarities due to ongoing adaptive mechanism for extrauterine life and deserves special attention in order to underline a specific management or clinical approach. The objective of this work was to verify clinical adaptations and biochemical balance of neonates during immediate period, with special reference to haematological, renal and metabolic functions. Neonatal puppies (n = 51) were physically examined for vitality and rectal temperature at birth, 5 and 60 min post‐birth. Blood was collected at birth and 60 min post‐birth for analysis of glucose, sodium, potassium, chlorine, blood urea nitrogen (BUN), haematocrit and haemoglobin. Neonatal vitality was lower at birth compared with 5 min and 60 min post‐birth. Progressive decline in rectal temperature (36.5 ± 0.3°C, 34.2 ± 0.2°C, 32.3 ± 0.5°C) was observed at birth, 5 min and 60 min post‐birth, respectively. Puppies presented slight hyponatremia (140.7 ± 0.5 mmol/L) at birth and hypopotassemia (3.5 ± 0.1 mmol/L) and blood urea nitrogen (13.1 ± 0.7 mg/dl) during the first hour, and high haematocrit (45.1 ± 1.0%) and haemoglobin (15.3 ± 0.3 g/dl) concentration. In conclusion, puppies had rapid evolution of vitality. Marked decrease in rectal temperature occurred at 5 min post‐birth. Haematological values of neonates immediately after birth reflected mainly the dam's blood status, not being useful for a blood panel at this time point. The peculiar pattern of BUN, sodium and potassium observed during transition period, suggested that specific reference range should be considered for neonatal puppies. 相似文献

The Isavirus is an orthomyxovirus with a genome composed of eight segments of negative single-strand RNA (−ssRNA). It has been proposed that the eight genomic segments of the Isavirus are organized as a ribonucleoprotein (RNP) complex called a minigenome, which contains all the viral RNA segments, a viral heterotrimeric polymerase and multiple copies of the viral nucleoprotein (NP). Here, we develop an Isavirus minigenome system and show the importance of the formation of active RNPs and the role of viral NP R189, R194, R302 and K325 residues in the NP RNA-binding domain in the context of RNPs. The results indicate it is possible to generate a minigenome in salmon cells, a composite ISAV RNPs with EGFP-based chimeric vRNA with heterotrimeric polymerase (PB1, PB2, PA) and NP protein using CMV-based auxiliary plasmids. It was also shown that NP R189, R194, R302 and K325 residues are important to generate viral mRNA from the constituted RNPs and a detectable reporter protein. This work is the first salmon cell-based minigenome assay for the Isavirus, which was evaluated by a bioinformatic and functional study of the NP protein in viral RNPs, which showed that correct NP-vRNA interaction is key to the functioning of RNPs. 相似文献

The clinical, clinicopathological and pathological findings are described in three Bull Terrier bitches with advanced renal disease. The bitches were less than four years old and showed variable presenting signs but anorexia, lethargy and polydipsia were the most frequent. All three dogs were azotaemic and isosthenuric. Urinary protein was measured in two of the three cases. Both were proteinuric. At necropsy all dogs had shrunken kidneys. Histological examination revealed nephron loss, atrophy of glomerular tufts, interstitial fibrosis, and mineralisation of basement membranes. The progressive renal disease in these dogs was similar to the condition reported in Bull Terriers in Australia, and is probably familial and inherited. 相似文献

Several outbreaks of anaemia, jaundice, abortion and mortality in cattle in New South Wales were attributed to the intracellular parasite, Theileria buffeli . Disease occurred predominantly in periparturient animals that had been moved from inland to coastal areas. Diagnosis was made via exclusion of other causes of haemolytic anaemia and observation of the parasite in blood smears. Treatments included both registered and non-registered products. There is a possibility of a new strain of Theileria sp. in Australia and the possible vectors encountered in NSW are discussed. 相似文献

Treatment options for equine sarcoids are briefly reviewed and the results of a retrospective study of 63 cases of equine sarcoid (66 lesions) treated by clinicians from the Rural Veterinary Centre, Camden, Australia from 1975 to 1993 presented. Five different treatments were employed in the management of these 66 lesions, including surgical excision alone or in combination with cryotherapy, radiotherapy, immunotherapy and tumour transfer to a subcutaneous site on the neck. The majority of cases were treated with surgical excision alone (18/66), excision followed by cryotherapy (31/66) and immunotherapy (16/66), with success rates of 28%, 42% and 81% respectively. Success was defined as no sign of recurrence of the lesion at the time of follow-up, at least 6 months later. 相似文献

The Tasmanian salmon industry had remained relatively free of major viral diseases until the emergence of pilchard orthomyxovirus (POMV). Originally isolated from wild pilchards, POMV is of concern to the industry as it can cause high mortality in farmed salmon (Salmo salar). Field observations suggest the virus can spread from pen to pen and between farms, but evidence of passive transmission in sea water was unclear. Our aim was to establish whether direct contact between infected and naïve fish was required for transmission, and to examine viral infection dynamics. Atlantic salmon post‐smolts were challenged with POMV by either direct exposure via cohabitation or indirect exposure via virus‐contaminated sea water. POMV was transmissible in sea water and direct contact between fish was not required for infection. Head kidney and heart presented the highest viral loads in early stages of infection. POMV survivors presented low viral loads in most tissues, but these remained relatively high in gills. A consistent feature was the infiltration of viral‐infected melanomacrophages in different tissues, suggesting an important role of these in the immune response to POMV. Understanding POMV transmission and host–pathogen interactions is key for the development of improved surveillance tools, transmission models and ultimately for disease prevention. 相似文献

The successful rehabilitation and release of raptor chicks can be challenging, especially when the chicks are still in the post-fledging dependency period. Here, we report on a recently fledged powerful owl chick that was held in care for 33 days before being successfully reunited with its parents. We document the steps undertaken during the entire process from collection from the wild to post-release monitoring and recommend clinical procedures for treatment of raptors entering veterinary facilities. Success of this rehabilitation was facilitated by early care and treatment for potential rodenticide poisoning, as well as the integration of citizen scientists monitoring the family unit in the field while the chick was in care and during the post-release period. Given the emerging evidence of widespread rodenticide poisoning in raptors both in Australia and globally, it is critical to suspect all raptors may have been exposed to anticoagulant rodenticides and commence treatment with vitamin K immediately. Routine treatment for rodenticides early increases the probability of successful recovery post-trauma as well as reducing the time in treatment as much as possible. 相似文献
